[jira] Commented: (STDCXX-586) [eccp/Linux] error #29 on #if _RWSTD_INSTANTIATE

["Martin Sebor (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/STDCXX-586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12534179 ] 

Martin Sebor commented on STDCXX-586:
-------------------------------------

The errors are caused by the WCHAR_T.cpp test failing due to the use of long long in the <wchar.h> Linux header, and the compiler operating in strict C++ 2003 mode (-AA). The config test unconditionally #includes <wchar.h> just in case wchar_t is a typedef. It should #include the header only when wchar_t is known not to be a fundamental type, i.e., when _RWSTD_NO_NATIVE_WCHAR_T is #defined in the generated config header.
